modelmap: paste a HuggingFace model ID, get an interactive architecture map

Show HN: Interactive, animated architecture of any HuggingFace models

modelmap.cc turns any HuggingFace model ID into an interactive architecture diagram—no weights downloaded. It instantiates the model on a meta device to get the structure, then runs a traced fake forward pass to infer tensor shapes. The homepage shows trending models like Qwen3.8-27B, DeepSeek-V4-Pro-0813, and Kimi-K3, plus classic reference architectures such as GPT-2, BERT, and DeepSeek-V3.1. Public repos work out of the box; gated ones work after adding a token. The post doesn't disclose whether it's open source, backend costs, or concurrency limits.

Why it matters: A practical Show HN tool that maps model architectures without downloading weights, featuring DeepSeek-V4-Pro and Kimi-K3 on the landing page. Hits H and K but lacks the discussion hook R requires — more of a bookmark than a conversation piece. Scores 72 at the featured thresh...
